No. Bulls (and other types of cattle) can see in blues and yellows, but not red.
Bulls would be the most obvious answer. Quite a lot of animals can only see in black and white.
Bulls don't like any colors, they just get annoyed when you wave a flag
... only if you are a nymphomaniac? [I don't see any reason why not. Its an animal its not going to attack you unless you're wearing red or leaking a lot] Bulls see only black & white! A red or yellow flag is only for show at bullfighting. Generally, never approach a bull without supervision of its owner. that goes for men too. Bulls can be unpredictable.
yes actually all dogs see black and white
Bulls come in a variety of colours, just like cows do. Bulls can be black and white, yellow, orange, black, brown, black and speckled, roan, leopard-type colour pattern, any colour with a white face, the list goes on.
Its not that they are only allowed it is just how the species is made they were made just to see black and white. It is something to do with the eye and how it is formed and stuff I don't know all about it but it is just the way that the species were made that they can only see black and white.
Yes, some people do see in black and white. This is called color blindness.
No, it just appears that way. White hairs are easier to see on black and black hairs are easier to see on white.
Dogs do see black and white. And some other colors too. Only not as well as humans.
No. only in black and white.
No, in colour
